Test Facility Capabilities

Large, Ambient Stage and/or Engine Test Facility

The B Test Complex consists of a dual-position; vertical, static-firing test stand designated as the B-1/B-2 test stand. Each test position is capable of static-firing test articles up to 33 feet diameter. The B-1/B-2 Test Stand is equipped with a 195-ton, main derrick lifting crane, with a 20-ton jib crane. The B-2 test position tested the first stage of the Saturn V rocket, as well as the Main Propulsion Test Article for the Space Shuttle Program. Testing for the Delta IV Common Booster Core Program was completed on the B-2 side in 2001. The position was modified for SLS (Space Launch System) Core Stage Green Run testing, conducted in 2020-2021. It now is being prepared to conduct Green Run testing of NASA’s new Exploration Upper Stage for future Artemis missions to the Moon.
